MASSACHUSETTS Letters Patent No. 85,218, dated December 22, 1868.

coMBrNA'I-rolv or NAME-PLATE AND LETTER-CHUTE.

The Schedule referred to'in these Letters Patent and making part of thename.

To all whom 'it 'may concern:

Be it known that we, ALEXANDER'M. DAMON and SLMEON G. LYFORD, both ofLowell, in the county of Middlesex, and State of Massachusetts, haveinvented certain new and useful Improvements in Name-Plates andLetter-Chutes combined, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,making part of this specication, in which- Figure l represents afront'elevation, and

- Figure2, a back elevation of a'nalne-plate, containing or constitutingour invention.

The object of our invention is to combine, in a neatand durable manner,ay letter-slide or chute, with an ordinary name-plate, such as areusually screwed or bolted to doors or. other convenient places, so astoconceal the former when not in use, and prevent the ingress of wind,dust, water, 85o.; and Y Such invention may be said to cons ist inproviding the plate'with an opening made through or into its flange,onthe upper side, as seen at J in fig. 2, shown by fed lines.

Also in the arrangementof its cover or cap A, in iig. l, iu its positionwhen raised for use, and which, by its construction and operation,conceals the opening through the door, and prevents cold air, water,85o., from entering the chute.

In constructing the cover or cap, we make use of the groove, assho'wn atP, in Figure 3, cross-section, into which is admitted the upper edge ofthe plate Q, thus making a water-tight joint.

We also use, in the further arrangement of the cap A, iig. 1, two armsor rods, which are made fastlto the cover, as shown at C, passingthrough a lportion ofthe upper flange ofthe plate T, iig. 2; alsothrough the projections L. These projections support the arms, and keepthem in their proper place.

Around the lower portion of these arms are axed spiral springs K, thestrength of which returns the cover to its place after it has been.raised for use;

gs. 3 -and '4, cross-sections 0 and R, so constructed i as to rest onthe bevelled lip or depressed flange J in iig. 2 of the plate, 'andwhich also serve to guide the entering letter through the chute in thedoor..

O, in fig. 3, shows a cross-section of thechute when closed.

R, in g. 4, shows'a cross-section of the cap when raised, opening thepassage S.

E, in iig. l, is the handle, by which the cover is l raised.

E, in fig. l, and H, in iig. 2, show an ornamental back to cover, whichmay or may not be used in our invention.

Having thus described our invention,

Vihat we claim, and'desire to secure by Letters Patent, is-

-1. The combined name-plate and cover, bywhich a letter-passage isconcealed.

2. -The'depressed ange I in iig.'2, and the bevelled projection. of thecover, which serves asa guide 'to the letterepassage in the door. v 3.The arms G, and spiral springs K, together with their arrangement, whenuse d for the purpose heretofore described.

4. The groove' P, substantially and for the purpose heretoforeexplained.
